Prof. of Viticulture, at Bordeaux Sciences Agro and @isvv-bordeaux.bsky.social‬, focused on adaptation of viticulture to climate change, drought tolerance, and sustainability.

👇From time to time I want to share some geeky 🤓 science articles that shed light on how grapevines really behave in the field. This one breaks down one of the fundamental reasons why two cordons of the same vine can differ even more than two separate vines. #viticulture #wine

Functional hydraulic sectoring in grapevines as evidenced by sap flow, dye infusion, leaf removal and micro-computed tomography

Grapevine xylem exhibited hydraulic sectoring, where transport was limited to discrete packets of the water-conducting vascular tissue. Detailed anatomical

👇I shared Yishai Netzer's commentary about irrigation in Bordeaux; here is a response. Also very thoughtful. The two are complementary; this not really being a "rebuttal". Also I know Yishai, being from Israel, is 110% conscious of water resource issues. #irrigation #viticulture

Water, water, not quite everywhere

👇A good example of expanding irrigation in EU viticulture. Here a drastic increase in Spain (y-axis is wine volume). We are working on a commentary piece with Vicente Pinilla and others and this trend has continued; production from irrigated vineyards has now surpassed rain-feed.

👇This grounded, thoughtful commentary by Yishai Netzer et al (a great researcher for whom I have a lot of respect) is actually a re-post from 2022. Here we are again. And gotta love the provocative headline; was that purposefully created to piss people off?😂 #wine #terroir

Bordeaux, Burgundy – it's time to irrigate!

👇100% Agree. The AOC regulations are antiquated. Although established with good intent; the climate in Bordeaux is completely different today. Most producers lack the acclaim to leave the AOC making exits like this important in that they could influence positive change for the remaining producers.

Celebrated producer Lafleur leaves the Pomerol and Bordeaux appellations. What are we to make of this news? wineanorak.com/2025/08/27/w...
